Environmental Friendly Products that Contain Hexagonal Boron Nitride

  1. 1. Environmental Friendly Products Contain Hexagonal Boron Nitride Gökçe Mehmet AY Prof.Dr.Nuran AY
  2. 2. World Population Increases World population from 1800 to 2100, based on UN 2004 projections (red, orange, green) and US Census Bureau historical estimates (black).* *http://en.wikipedia.org/wiki/World_Population 10/10/2011
  3. 3. Energy Consumption Increases Rate of world energy usage in terawatts (TW), 1965–2005 * * http://en.wikipedia.org/wiki/World_Energy 10/10/2011
  4. 4. Energy by sector * http://en.wikipedia.org/wiki/World_Energy 10/10/2011 TWh % Industry 27,273 27.8% Transport 26,742 27.3% Residential and Service 35,319 36.0% Non-Energy use 8,688 8.9%
  5. 5. Transportation: Internal Combustion Engine
  6. 6. Energy Loss by Friction <ul><li>Since the time of pharaohs some techniques are used to prevent friction. </li></ul><ul><li>Prevented friction means free energy </li></ul>
  7. 7. Lubricants <ul><li>Liquid </li></ul><ul><li>Solid </li></ul><ul><li>Gaseous </li></ul><ul><li>or mixture of these </li></ul>
  8. 8. To improve lubrication Additives are used with lubricants Those additives should be <ul><li>Inert </li></ul><ul><li>No residue </li></ul><ul><li>No filter blockage </li></ul><ul><li>No corrosion </li></ul><ul><li>No harmful emissions </li></ul>
  9. 9. Solid Lubricants * T. Mang, Lubricants and lubrication, 2nd ed. Weinheim , 2006, p695.
  10. 10. Boron Nitride <ul><li>Formed of 1:1 reaction of Boron and Nitrogen Elements </li></ul><ul><li>Is Artificial </li></ul><ul><li>Has three different crystal structures resembling carbon polymorphs </li></ul>
  11. 11. According to Crystal Structure <ul><li>cBN; a hard zinc blend form, ultrahard material </li></ul><ul><li>hBN; a soft graphitic form smilar in structure to graphite </li></ul><ul><li>wBN ; synthesised at high pressure </li></ul>
  12. 12. Properties of Hexagonal Boron Nitride <ul><li>Withstands 900 o C at oxidizing environments </li></ul><ul><li>Is a good solid lubricant </li></ul><ul><li>Has low friction coefficient </li></ul><ul><li>Melts at 3000 o C </li></ul><ul><li>Has high thermal conductivity </li></ul><ul><li>Is electrical insulator </li></ul>
  13. 13. Boron Nitride in Turkey <ul><li>At 2006 BORTEK produced Boron Nitride at industrial level with support from BOREN. </li></ul><ul><li>BORTEK produced engine and transmission oil additives with support from SAN-TEZ program of Republic of Turkey Ministry of Science, Industry and Technology </li></ul>
  14. 14. Boronmax tests <ul><li>A vehicle using gas </li></ul><ul><li>4.64% decrease in fuel consumption </li></ul><ul><li>ASTM D5183-05 test </li></ul><ul><li>14% decrease in friction </li></ul><ul><li>20% increase in film load capacity </li></ul>
  15. 15. Boronmax M1002 <ul><li>Used in industrial power transmission parts </li></ul><ul><li>A study conducted at Çanakkale Seramik showed more than 10% decrease in electricity consumption </li></ul>
  16. 16. BORTEK composite coating <ul><li>Self lubricating parts </li></ul><ul><li>Reduction in wear on moving parts </li></ul><ul><li>Reduction in sticking </li></ul>Steel Part Coating
  17. 17. hBN containing products Reduced Friction Reduced Wear Reduced Energy Reduced Emissions
  18. 18. We'd like to thank to <ul><li>Republic of Turkey Ministry of Science, Industry and Technology </li></ul><ul><li>Turkish National Boron Research Institute </li></ul><ul><li>for their supports </li></ul>
